SPECIFICATION forming part of Letters Patent No. 658,078, dated September 18, 1900.

\ Application filed December 28. 1899. Serial No. 741,817. (No model'.)

To all whom, it may concern:

Be it known that I, ARNE VICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Miter-Boxes, of which the following is a specification.

The object of this invention is the production of an improved miter-box.

In the accompanying drawings, Figure 1 is a plan view of this miter-box, showing by dotted lines the saw in position, also showing in dotted lines the saw-carrying arm turned to its greatest angle. Fig. 2 is an under face view of the miter-box. Fig. 3 is a transverse vertical central section through the miterbox. Fig. 4 is a horizontal section through the central turn-table of the miter-box. Fig. 5 is an end elevation of the forward guideblocks for the handle end of the saw. Fig. 6 is an under face view of the guide-blocks for the outer end of the saw.

Like letters of reference indicatecorre spouding parts throughout the several views.

In the construction of the miter-box Iprovide the supporting-frame A, having the sustaining-feet A rigidly fixed to the frame, at the outer ends thereof, which feet are provided with the perforations A by means of which the miter-box. is secured to a bench or any other suitable means of'support. The middle of the frame is provided with the opening A for the reception of a pivotal stud, and a' dial-plate A is formed integral with said frame and concentric with the opening A". Two bed-pieces B are secured to the upper face of the supporting-frame A, and the back pieces B are secured to the bed-pieces B, said back pieces rising somewhat above the bed-pieces and forming a right angle with the bed-pieces B.

A saw-carrying arm 0 is located below the dial-plate and lies in contact with the under face thereof. A stud 0, having an enlarged upper end, pivotally connects the saw-carrying arm 0 with the dial-plate A said stud passing through the opening A and also through a perforation in the saw-carrying arm 0. This stud is of reduced diameter whereit passes through said saw-carrying arm C and is screw-threaded at its lower end to receive a nut 0 The saw-carrying arm 0 is provided with the downwardly-exteuding ears 0 between which are pivoted the hand-lever G which lever bears at its forward end the integral stud C extending upward through an opening C in the saw-carrying arm and frietionally engaging the um der side of the dial-plate A A flat spring is secured by means of the screwO? to the under side of thesaw-carrying arm (1, its purpose being to hold the integral stud in engagement with the under side of said dial-plate A When it is desirable to move the saw-carrying arm to change its angle with relation tothe dial-plate A the lever C is raised by the fingers of the operator, and the stud O is withdrawn from its frictional engagement with the under face of the dial-plate A 1 D is a turn-table of circular outline mount.- ed upon the stud O, and therefore being fixed with relation to the saw-carrying arm 0. It

is provided with an indicatorD, intended to be placed into coincidence with figures upon the dial-plate A in order to indicate the angle at which the saw-carrying arm 0 stands with relation to the back pieces B.

D are'two pairs of screw-threaded perforations in the saw-carrying arm 0, and D are two similar perforations, which said perforations afford means for securing the guideblocks, to be later described herein, rigidly to the upper face of the saw-carrying arm 0.

D is a facing of wood or other suitable material for the turn-table D. It is provided with a diametrio channelin its face, and this channelis filled with a tightly-fitting block of Wood D held in position by the screw D passing. through said facing D and engaging said block. This block is intended to be removed and replaced when after a considerable amount of use it has become Worn by the contact-of the teeth of the saw. I

E E are guide-blocks for the handle end of the saw-blade. Each is composed of a wedgeshaped piece of wood,and they are set slightly apart to leave a space between them for the passage of the saw-blade. A right-angled bracket E holds said blocks rigidly in position and forms a means of adjustably connecting them with the saw-carrying arm 0. This bracket is provided with the elongated openings E in its base, and has the thumb screws E for securing said bracket to the saw-carrying arm. The two pairs of screwthreaded perforations D provide means for a considerable ad justmentof the guide-blocks to or from the turn-table D, and the transversely-elongated openings E in the bracket E provide for the adjustment of the blocks with relation to each other. A stop-block E for receiving the saw is secured to the lower side of the guide-blocks E E.

F F are two similar guide-blocks secured rigidly to their supporting righ t-angled bracket F and capable of a transverse adjustment with relation to each other for allowing more or less space between them for the support of the saw-blade. The base of the right-angled bracket F is provided with the elongated openings F for the reception of thumb-screws F intended to enter the screw-threaded perforations D near the rear end of the saw-carrying arm C.

F is a block rigidly secured to one of said guide-blocks F by the screw F and having a slotted opening F providing an adjustable engagement between the other one of said blocks F and the securing-block F This block F may be removed and renewed when worn by contact with the saw-teeth.

G are two stops, each having a pivotal connection with the under face of one of the upwardly-extending back pieces B. The length of these stops is adjustable by means of the wood-screwsG, turned into their free ends. When a considerable number of pieces of molding are to be cut at a certain angle, the stops G are arranged to limit the movement of the saw-carrying arm G. Those shown in Fig. 2 are represented as set to stop the sawcarrying arm at an angle of forty-five degrees with the length of the back pieces B.

In operation this miter-box is secured to a bench or any other suitable means of support and apiece of molding placed upon the bed-pieces B and held firmly against the back pieces B. A common crosseut saw is inserted between the guide-blocks E E and F F and the saw and saw-carrying arm turned to the proper angle, which angle is determined by the indicator D upon the dial-plate A The molding is sawed off upon the desired angle, when the turn-table maybe rotated to any other angIe by raising the lever C". The guide-blocks E E and F F may be adjusted with relation to each other and easily removed from their supporting-brackets E and F, respectively.

I claim as my invention 1. In a miter-box, in combination, a supporting-frame; bed-pieces and back pieces on opposite ends of the supporting-frame, the bed-pieces having a space between them; a

saw-carrying arm having a pivotal connection with said supporting-frame; a turn-table fixed with relation to said arm, and lying in the space between said bed-pieces, its surface being flush with the surfaces of said bedpieces, which turn-table is adapted to rotate with the saw-carrying arm independently of the bed-pieces and back pieces; and means for forming a frictional engagement between the saw-carrying arm and the supportingframe.

2. In a miter-box, in combination, a supporting-frame having a dial-plate; bed-pieces and back pieces for the frame; a saw-carrying arm havingapivotal connection with said frame concentric with the dialplate; a turntable fixed with relation to said arm; a lever pivotally mounted on said arm, having a frictional engagemen t with the supporting-frame; a spring for said lever; and means on the sawcarrying arm for supporting a saw.

3. In a miter-box, in combination, a supporting-frame; bed-pieces and back pieces on opposite ends of the supporting-frame, the bed-pieces having a space between them; a dial-plate on the supporting-frame, within said space between the bed-pieces; a sawcarrying arm having a pivotal connection with the frame; a turn-table fixed with relation to said saw-carrying arm, and lying over said dial-plate, within the space between said bedpieces, which turntable is adapted to rotate with the saw-carrying arm independently of the bed-pieces and back pieces, and has an indicator for said dial-plate; two brackets having an adjustable connection with said saw-carrying arm; and guide-blocks. on each of said brackets for receiving a saw.

4. In a miter-box, in combination, a supporting-frame having a dial-plate formed integral therewith; bed-pieces and back pieces for the frame, the bed-pieces being secured to said frame on opposite sides of the dialplate; a saw-carrying arm; a turn-table over said dial-plate; a stud connecting the arm and the turn-table rigidly together, which stud has a pivotal engagement with the supporting-frame; stops for limiting the pivotal movement of the saw-carrying arm; which turn-table is adapted to rotate with the sawcarrying arm independently of the bed-pieces and back pieces; two brackets having an adjustable connection with the saw-carrying arm; and guide-blocks on each of said brackets for supporting a saw between them.
